The conference will be held at the University of Chicago Gleacher Center 5 October (9 am) through 8 October (3 pm) 2019.

Is cosmology on the verge of a fundamental description of the Universe from a tiny fraction of a second after the big bang until today based upon LCDM, or is it on the cusp of major disruption and re-organization of our understanding of the Universe? Eight cosmic controversies – the value(s) the Hubble constant, viability of CDM, cause of cosmic acceleration, validity of inflation, the existence of a dark matter particle, clarity about the multiverse, origin of ordinary matter, and other loose ends in the paradigm – have much to say about the direction cosmology will take in the next decade and may be the answer the question above. Our cosmology conclave will focus on these controversies and address how best to resolve them.
